The property shall be omitted if LE is not enabled, I guess that was
the intent of optional but saying it would return NotSupport means
otherwise.

I guess the intend here would be to have a prefered PHY for LE, but I
wonder if this would really help since different profiles/service may
have different preferences, also by being an array I assume one would
need to the enter in the preferred order which should probably be
stated and again depending on the use case this could be a config
setting in main.conf instead so it is applied globally to all devices
by drivers can overwrite it with their own preferences.
